# Log files

How to access the Diffblue Cover Plugin for IntelliJ log files, to better understand the tool's behavior and for debugging purposes.

## User logs

Cover Plugin creates and maintains a user log file, `user.log`, in the following locations:

**Windows:** `%USERPROFILE%\AppData\Local\Temp\diffblue\log`

**Linux:** `/tmp/diffblue/log`

**macOS:** `$TMPDIR/diffblue/log`

## Support logs

Cover Plugin also creates a `support.log` log file, in the same directory, which is only relevant to the Diffblue support team. If you raise a support issue then you may be asked to provide this log file.

## Accessing logs

Cover Plugin provides simple access to logs via the [Diffblue Cover tool window](/features/cover-plugin/writing-tests/diffblue-cover-tool-window.md#open-logs). After writing tests, simply look for the Open Logs button and select your desired action.
